I take the following medications: Losartin 100mg/12.5 mg for (HBP), Rabeprazole 20mg for (acid reflux), Lorazepam 0.5mg for (Anxiety), Vitamin B12 1000mcg, D3 2000IU, and Calcium 600mg. All of them once a day. Do I need to take Magnesium while taking the above meds? Will it cause side effects? If so, what effects?
